RESUMO
Iridociliary cysts are often found in patients as an incidental finding during a routine ophthalmic evaluation and if asymptomatic do not require any treatment per se. However, these are often mistaken as iris melanoma and the patient is managed accordingly causing a great deal of inconvenience to the patient as well as the doctor. A 69 year old male presented to the ophthalmic out-patients department for routine ophthalmic evaluation. On examination, he is best corrected visual acuity was 6/9, N6 in both eyes. Post-mydriasis evaluation showed a Grade II nuclear cataract in both eyes. There was a smooth, pigmented mass with a rounded surface projecting from behind the iris resembling an iris melanoma. On further evaluation, he was found to have multiple ciliary body cysts. Ultrasound biomicroscopy is a valuable technique in diagnosing iridociliary cysts
